Filed Aug. 19, 1959, Ser. No. 834,729 Qlaims. (til. 5tl2ll9) The present invention generally relates to novel structural details of sheet metal roofing and more particularly to a joint for securing the edges of panels or units of sheet metal roofing together while sealing the same.

In the application of sheet metal roofing to buildings or the like, there has been an outstanding problem of connecting the panels of sheet metal in such a manner that the joint will be retained in a waterproof condition for an extended length of time. Various methods have been employed in joining the edges of the sheet metal panel including the overlapping and interlocking of the panels as well as the actual connection of the panels such as by soldering or the like. While soldering provides a waterproof condition, it also provides a rigid relationship between the panels which will not allow for expansion and contraction wmch occurs in roof panels due to change in temperatures. When this occurs, the joint between the panels, even though soldered, will quite often be ruptured thus eliminating the waterproof condition thereof. Therefore, it is the primary object of this invention to provide a simple and inexpensive method of joining sheet metal together for use as a roofing material by providing a joint between said sheets of metal which includes a plastic material that will insure expansion and contraction without the rigidity of :a soldered joint and also maintain the watertight relationship between the panels.

Another object of the present invention is to provide a method of joining metal roofing panels in which the adjacent edges are generally bent to define a channel-shaped area or trough-shaped area for receiving a mastic with the edges of some portion of the edges of each panel being embedded in plastic material disposed in the trough or channel-shaped area for effectively sealing the panels together.

Another important object of the present invention is to provide a method of joining sheet metal roofing panels in which several variations of the basic concept are provided with all of these concepts providing an expansion joint due to the particular bend for-med in the edges of the panels and also due to the mastic or plastic material disposed in the trough shaped area and also due to the disposal of edge portions of the channel in the mastic for sealing relation.

A further important feature of the present invention is to provide a method of joining sheet metal roofing panels which incorporates a structure which may be easily formed on the job by suitable simple tools with the structure being extremely simple, easy to make and use, efiicient in use, Well adapted for which the same is intended and generally inexpensive to manufacture.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and opertation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 15 is a perspective view of the corner joint.

Referring now specifically to FIGURES l7, one form of the present invention is illustrated for joining rectangular sheet metal roofing panels 19 and 12 together and mounting the same on sheeting 14- or the like.

Each of the panels 14 is provided with a peripheral upwardly inclined and outwardly extending edge portion 16 terminating in a downwardly extending vertical wall portion 13 with the vertical wall portion 18 extending peripherally around the panel Ill and having an outwardly extending horizontal flange 251! at the bottom edge thereof. The outwardly extending horizontal flange 20 terminates in an upwardly inclined flange 22 which converges towards the vertical wall 18 and which has an upper edge 24 terminating below the upper edge of the vertical wall portion 18 which is in the form of a bend 26 connecting the vertical wall portion 18 to the inclined portion 15.

panel 12 is provided with a peripheral upwardly inclined flange or portion 28 which terminates at its upper end with a horizontally extendhrg peri heral flange 3%. The flange terminates in the depending vertical wall portion 32 having the lower edge terminating in a reversely sent port it 34. The lower edge of the vertical wall portion 32 is disposed above the plane of the panel and is adapted to be disposed within the trough or U-shaped channel formed by the vertical Wall portion 125, Z6 and fiange 22 as illustrated in FIGURE 4.

Before application of panels 12, the gutter or trough around the margin of panels at? are filled with mastic 35 and the panels 12 are then placed in their proper location in relation to panels ll) and the marginal depending legs 32 are pressed into the mastic in the gutter of the panels it thus forming a seal about the periphery of the panels with portion 34* forming a key in the mastic.

At the corner between the panels, it will be seen in FIGURE 5 that a spacer 38 of inverted U-shaped construction is disposed between the panels 1% with the spacer 38 having downwardly extending and converging legs 46 received within the upwardly opening troughs or gutters formed on the panels ill. The spacer 38 not only serves to retain the panels 1%? in exact spaced relation 3 but also se ves as a baffie against leakage through the crack between diagonally disposed panels 12.

As shown in FZGURE 7, each corner of the panels 12 has a radial extension 42 il-h dependin legs 44 forming continuations of the legs 32 with the extension 4-2 forming a continuation of the flange The legs 44 are curved to coniorm to the curvature of the gutters or troughs formed in the panel and are received therein as illustrated in FIGURE 5. Also, the outer edge of the extension 42. is provided with an upturned tab as which is spaced from a corresponding tab 46 on a diagonally opposed panel 12. whereby mastic as is also disposed beween the abutment 4d and between the extension 42 and the spacer 38 and between the free edges of the legs 44 and the vertical wall portions 13 and the flanges 22 and inturned legs whereby the mastic cooperates with all of the various flanges for retaining the panels in sealed relation.

Referring now particularly to FIGURES 8-15, the roof panels 118 and 120 are placed on the roof in consecutive order with the roof panels 113 and each having a longitudinally extending and upstanding U-shaped in verted member or rib 121 thereon in spaced relation to an upturned and slightly outwardly inclined flange 122 which defines a channel shaped area 124 therebetween. The panel 118 is secured to the underlying roof structure 126 by a plurality of clips 123 having a fastener 13d securing it to the roof structure 126 and having a hook shaped end 132 for engagement over the upper edge of the upturned flange 122. Thus, when the flanges 3.22 are disposed in adjacent relation to each other, they define a generally V-shaped trough for receiving mastic 134 which is also received in a generally inverted U-shaped cap 136 that has the depending side walls 133 converging inwardly with the side walls 133 being spaced from the flanges 122 with mastic 134 therebetween.

The cap 136 is filled with mastic and is pressed over the two upstanding flanges 122 with the final condition of the components of the joint being illustrated in FIG- URE 13.

FIGURE 14 is a plan view of the joint structure of the present invention for joining the corners of adjacent panels 140, 142, 144 and 146 each of which includes the inverted U-shaped rib 148 and the upturned free edge, flange 156, see FIG. 10, which is the same as the structure mentioned in connection with panels 118 and 120.

FIGURE 15 illustrates the cap which includes a generally cruciform panel 152 having depending flanges 154 converging towards each other similar to the flanges 138 but with the flanges being disposed on all of the side edges of the member 152.

FIGURE 11 illustrates a panel 153 having an upstanding inverted U-shaped rib res around the periphery thereof which rib includes an outwardly extending flange 162 terminating in an upwardly and inwardly inclined flange 164 which is adapted to receive the cruciform type of cap shown in FIGURE 8 including sheet member 166 which has depending flanges 168 on each side edge of each arm of the cruciform body 165. The lie iges 163 are reversely bent as indicated by the numeral 17d.

FIGURE 9 illustrates the form of the invention described in FIGURE 8 and also includes the use of panels 172 and 1W1 and the panels 172 17 have raised portions 194 and the mastic will effectively seal the joints between the closure member 196 similar to the member 1 6 with the mastic 128 being disposed completely within the cap 1% and also exteriorly of and interiorly or" the internal flanges or ribs respectively. After the mastic is hardened, the wedge shape or" flange E58 and the wedge shape of the channel formed by flanges 1'52 and 164 renders the components completely interlocked.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not des red to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equ valents may be resorted to, falling within the scope or" the invention as claimed.
